通过对大川地热进行的可控源大地音频测量获得的CSAMT进行数据处理,采用VOXLER软件建立三维等值面模型,从三度空间对区内地质体电性特征进行解译,通过三维模型区分不同电阻率地质体的空间分布,根据xy面上的切片解译出深剖断裂构造,在xz面上解译出深部存在承压水层,并指出本区高温地热水的寻找方向。
The data of CSAMT obtained from controllable source geophone sounding in Ochuan geothermal field are processed. The VOXLER software is used to establish the three-dimensional isosurface model. The electrical characteristics of geologic bodies in the area are interpreted from three-dimensional space. The three-dimensional model distinguishes According to the spatial distribution of the resistivity geologic body, the deep-fault fracture structure is interpreted according to the slice on the xy plane, and the deep existing confined water layer is interpreted on the xz plane. The direction of looking for the hot geothermal water in this area is also pointed out.
